Just about perfect
Perfect timeless calculator on my high resolution iPhone Air. Arguably better than the actual calculator

15C Emulator - Great App!
Nothing ever beats the real thing, but if you are in a pinch and don’t have your 15C in front of you, this emulator is as good as it gets.

Fantastic App. RPN IS GREAT
This is a fantastic App and I find it absolutely fantastic software version of the original hardware HP Calculator.
I used this very hardware HP calculator for many years when it first came out and it was a must have. Unfortunately I lost it.
It was a life saver when I discovered your app.
My grateful thanks for this wonderful app.
I simply couldn’t go without it.

HP 15c
Great reproduction of the classic! Works great in the iPhone 6. I'm an electrical engineer who still depends on my 15c. Main complaint is the very loud clicks for the buttons which is very annoying, especially since there is no way to disable or lower its volume from within the ap. Turning off the ringer on the side of the iPhone to disable sound works but is unacceptable. Hopefully HP will fix this soon - especially if enough of us complain. However, the calculating capabilities work exactly as the original.

Just Like Old Times
I have been an engineer for over 30 years. Always used HO 15. This app is even better than original calculator.
